Abstract
A display device and a driving method are disclosed. The display device includes a plurality of pixel areas disposed in a display panel. Each pixel area includes at least one row of pixel units. The display panel further includes a plurality of collecting modules, a comparing module, and a processing module. Each collecting module is connected to the pixel units in each pixel area and configured to obtain and transmit input power voltage signals of the pixel units in a corresponding pixel area to the comparing module. The comparing module receives and compares the input power voltage signals with a base voltage respectively and transmits comparison results to the processing module respectively. The processing module adjusts data voltages of the pixel units in the corresponding pixel area respectively based on the comparison results in order to compensate the pixel units in the corresponding pixel area for resistive voltage drop differences.
